Fisheries

The estimated potential of tuna is needed in fishing activities, to maintain the sustainability and sustainability of tuna resources. This research was carried out at the PPN in Palabuhanratu, Sukabumi, West Java, in May 2019, using a quantitative descriptive analysis method by calculating the production results with capture effort. This research aims to analyze the production of annual catches, estimate the maximum sustainable potential and estimate the utilization rate of yellowfin tuna. The data used in this study are production data and data on the number of fishing trips by calculating productivity, maximum sustainable potential, and utilization rates. CPUE (Catch per Unit Effort) shows that the average annual production of yellowfin tuna is 295.408 tons with an average fishing effort of 1348128 trips per year. Based on the calculation using the Schaefer model, the estimated maximum sustainable potential or MSY of yellowfin tuna is 517.381 tons per year with a total allowable catch of 413.904 tons. The average percentage value of the utilization rate of yellowfin tuna resources is 71%, so it is categorized as moderate. Port of the Indonesian Fishery in Palabuhanratu in 2013-2017 which has not been overexploited, it is still possible to make additional fishing efforts but must be done in close monitoring to maintain the sustainability and sustainability of the yellowfin tuna resources to remain stable.
